Parsley Health Store — UCP / MCP Agent Commerce
The agent-callable surface of Parsley Health's direct-to-consumer supplement store. A live, anonymous Universal Commerce Protocol MCP endpoint exposes thirteen tools for catalog search, product lookup, cart construction, checkout and order retrieval, with JSON Schema 2020-12 input schemas returned by tools/list. The same host serves an anonymous Shopify Storefront GraphQL endpoint, unauthenticated storefront JSON endpoints, an llms.txt and agents.md aimed at agents, a UCP merchant profile, and OpenID Connect / OAuth 2.0 authorization-server discovery for store customer accounts. The surface is platform-provided by Shopify under Parsley Health's own hostname (shop id 24996151350) rather than engineered by Parsley Health, and it covers retail supplement purchase only — no clinical, member, appointment or lab data is reachable. Completing checkout requires contemporaneous human buyer approval per the store's own published agent rules.
